I was watching TV and I stumbled across an advert for a "salt room." Apparantly, its a treatment that lasts a few weeks to "aide augment treatment of virtually all respiratory problems."
It started me thinking about living at sea, especially the next comment: "Salt therapy also has preventative and invigorating effects on healthy people."
Is this why sailors tend to be healthy, happy people?
